• A piece of correspondence on the letters page expressed the view that an attempt by Jewish activists on a sailing boat to break the sea blockade around Gaza this week had been important in "reasserting the Jewish tradition of standing up for the victims of injustice" (30 September, page 35).

• Purporting to show Senegal – one of the countries whose fishermen, we reported, have been found working in conditions tantamount to forced labour off west Africa – a map instead showed Mauritania (Modern-day slavery, 30 September, page 3).

• A commentary on the Liberal Democrats in government meant to refer to the party's focus on reducing carbon emissions by 80% (measured from 1990 levels) by 2050, not from 2050 (The point of government, 18 September, page 31).

• Recounting how Ed Miliband's mother stood outside the play My Name Is Rachel Corrie handing out pro-Palestinian flyers, we misnamed the play Who Killed Rachel Corrie? (Man in the middle, 27 September, page 6).

• A cycling piece harked back to a year when some riders in the (then Kellogg's) Tour of Britain surrendered in the face of Swansea's tough Constitution Hill. We should have dated the episode to 1993 rather than 1994 (Sky left grounded by Albasini's spurt up the hill, 14 September, page 8, Sport).
